In an excerpt of Out of Time, a new book on “the pleasures and perils of ageing,” author Lynne Segalmakes a case that many iconic male writers — among them Philip Roth, John Updike and Martin Amis — display in their works a belief that the slow loss of virility is one of the most tragic effects of growing older for men. Citing passages from Toward the End of Time and Portnoy’s Complaint, she finds evidence that these writers’ depictions of masculinity reveal “obdurate social hierarchies of gender and ageing.” (Related: Keith Meattoon advice you can glean from Philip Roth’s work.)
